BiTeEr lump.
This is a roughly bullet-shaped lump of what is described on the envelope it came in as about half Bi, half Te, and a trace of Er. Actually the exact percentages are given, but in deference to whoever discarded this item I'm not listing them, in case they represent some kind of secret formula for making really good lumps of metal, or something. Ethan seems to have gotten into a batch of strange tellurium compounds someone at his university was throwing away: I'm going to be listing more of them soon.
Reader Anders Mikkelsen suggests that this alloy may have been used in research into Peltier junctions.Source:Ethan CurrensContributor:Ethan CurrensAcquired:18 March, 2007Text Updated:28 March, 2009Price: DonatedSize: 1"Composition:BiTeEr
